Problems solved by technology

[0002] At present, mobile phones are developing in the direction of narrow bezels and large screen-to-body ratios. With the continuous expansion of screen-to-body ratios, the functional devices of mobile phones are arranged more closely, such as proximity sensors and antennas. Proximity sensors may be arranged in the clearance area of ​​antennas. In, the proximity sensor is susceptible to interference from antenna radiation and has poor reliability

Abstract

The invention discloses an anti-interference circuit structure and a mobile terminal. The anti-interference circuit structure comprises an antenna and a proximity sensor. The antenna is used for transmitting out a radiation signal. The proximity sensor comprises a transmitter and a receiver which are connected mutually; the transmitter is used for transmitting a detection signal; and the receiveris used for receiving the reflected detection signal. The anti-interference circuit structure further comprises a filtering capacitor; one end of the filtering capacitor is connected between the transmitter and the receiver; the other end of the filtering capacitor is grounded; and the filtering capacitor is used for filtering out interference of the radiation signal to the transmitter. The filtering capacitor can filter out interference of the radiation signal to the transmitter, and thus, transmission intensity of the transmitter is easy to control and working reliability of the proximity sensor is higher.

Description

technical field [0001] The present invention relates to the technical field of electronic equipment, and more specifically, to an anti-jamming circuit structure and a mobile terminal. Background technique [0002] At present, mobile phones are developing in the direction of narrow bezels and large screen-to-body ratios. With the continuous expansion of screen-to-body ratios, the functional devices of mobile phones are arranged more closely, such as proximity sensors and antennas. Proximity sensors may be arranged in the clearance area of ​​antennas. As a result, the proximity sensor is susceptible to interference from antenna radiation and has poor reliability. Contents of the invention [0003] Embodiments of the present invention provide an anti-jamming circuit structure and a mobile terminal. [0004] The anti-jamming circuit structure of the embodiment of the present invention includes an antenna and a proximity sensor, the antenna is used to emit radiation signals, t...
